Oral supplementation of α-lipoic acid (ALA), magnesium, vitamin B6 and vitamin D stabilizes cervical changes in women presenting risk factors for preterm birth.

OBJECTIVE: Recently, the PTB risk has been related to the objective measurement of cervical length (CL), since a CL of less than 25 mm is an accurate predictor of increased risk of PTB. Primary prevention of preterm labor is based on the early identification of symptoms and on pharmacological treatments with tocolytic drugs for inhibition of uterine contractions that are associated with a shortening of the cervix. Unfortunately, most of these drugs have important side effects. PATIENTS AND METHODS: This study aimed to evaluate whether the administration of a combination of oral α-lipoic acid (ALA), magnesium, vitamin B6 and vitamin D to pregnant women presenting risk factors for PTB could reduce the rate of cervical shortening at 19-22 weeks of gestational age. RESULTS: A total of 122 women attending the first-trimester aneuploidy screening at 11-14 weeks of pregnancy and presenting risk factors for PTB were included in the study. Cervical length significantly decreased in the control group compared with the treatment group (-3.86 ± 1.97 vs. 1.50 ± 1.26; p=0.02). Although the rate of preterm birth did not significantly decrease (9.5% vs. 5.1%), admission for threatened PTB was statistically reduced in the treatment group compared with the control group (3.4% vs. 14.3%). CONCLUSIONS: Oral supplementation of ALA, magnesium, vitamin B6 and vitamin D significantly counteracted cervix shortening in pregnant women presenting risk factors for PTB.

Hidradenitis suppurativa in a prepubertal case series: a call for specific guidelines.

Hidradenitis suppurativa (HS) is a chronic, recurrent, inflammatory disease associated with a high physical and psychological burden. It is a disorder of the infundibular segment of the pilosebaceous unit, characterized by subcutaneous nodules, abscesses, sinus tracts and scar formation on the intertriginous and apocrine-bearing areas. HS is quite rare in young and prepubertal children. It usually begins after puberty, but several reports of prepubertal HS onset have been described. These cases are strongly linked to hormonal disorders and genetic susceptibility. Specific guidelines for prepubertal patients are still lacking, so further studies are warranted to better delineate a tailored approach. This paper aims to summarize the most significant aspects, as well as the most recent information about the epidemiology, pathogenesis, clinical features, diagnosis, comorbidities and treatment of paediatric HS. In addition, we report our clinical experience in managing HS in a group of eight prepubertal patients based on systemic antibiotics (azithromycin) and zinc oral supplementation.

Detection of D-penicillamine in skin lesions in a case of dermal elastosis after a previous long-term treatment for Wilson's disease.

BACKGROUND: Skin adverse events associated with D-Penicillamine (DPA) are common and multi-faceted, although the presence of DPA or its metabolites has never been documented in the skin, because of inherent difficulties in determining its tissue levels. Thus, the association between DPA and DPA-related dermatoses has been only hypothesized on the basis of careful history, clinical observation and typical histopathological findings. OBJECTIVE: To detect DPA in biopsy specimens in a unique case of 25-year-late-onset elastosis perforans serpiginosa and pseudo-pseudoxanthoma elasticum associated with a history of long-term high dose DPA, by applying a recently described analytical method to assess the presence of DPA in skin. METHODS: We used a reliable analytical method based on high-performance liquid chromatography coupled with amperometric detection to look for the presence of DPA in skin biopsy specimens. RESULTS: A chromatographic peak corresponding to DPA was evidenced in some affected skin samples collected from the patient. CONCLUSION: We documented the effective presence and the persistence after 25 years of DPA in the skin of a woman affected by elastotic cutaneous change due to a long-term therapy with DPA. This report provides further evidence of the relationship between DPA deposit in affected skin and clinical manifestation.

Efficacy and tolerability of a cream containing AR-GG27® (sorbityl furfural palmitate) in the treatment of mild/moderate childhood atopic dermatitis associated with pityriasis alba. A double-blind, placebo-controlled clinical trial.

AIM: Pityriasis alba (PA) is a skin disorder characterized by finely scaly, hypopigmented patches, typical of childhood, that also represents an atopic dermatitis (AD) minor sign according to Hanifin and Rajka criteria. It may be isolated or associated with AD representing, sometimes an atypical manifestation of AD during the long-term follow-up of the disease. Aim of the study was to evaluate of the efficacy and tolerability of AR-GG27® (sorbityl furfural palmitate) cream in the treatment of childhood mild or moderate AD associated with PA. METHODS: The trial is a single center, double-blind, randomized, placebo-controlled study. The study included patients of both sexes, aged between two months and 15 years, suffering from mild and moderate AD always associated with PA. Xerosis was present in all patients. The treatment with topical steroids or topical calcineurin inhibitors (TIMs) had to be suspended for at least 15 days. Any systemic therapy and phototherapy or sun exposure were withdrawn at least 30 days before. Emollients were stopped at least seven days before. During the trial, no other local or systemic treatments were allowed, as well as sun exposure. Patients affected by AD with viral, bacterial or fungal overinfection or patients with diabetes mellitus, severe systemic diseases or intolerance to one or more components of the product were excluded. The primary endpoint was the evaluation of the average change in the Investigator Global Assessment (IGA) after 15 and 30 days of treatment. The second endpoint was the evaluation of severity of three different clinical signs: erythema, excoriation desquamation, using a subjective five-point scale. Changes in pruritus severity was also considered during the entire period of treatment, through the use of a Visual Analogue Scale (VAS). A P<0.05, two tailed was considered as statistically significant. RESULTS: After 15 and 30 days there was a statistically significant difference in the group treated with AR-GG27®, compared to the placebo (respectively, P=0.0007 and P=0.005). After 15 days of treatment, itching was clearly reduced in AR-GG27® treated group compared with the placebo, both in the study population (P=0.01) and in patients where the symptom was present from the beginning (P=0.05). CONCLUSION: AR-GG27® showed a beneficial action associated with high compliance and tolerability in dermatological skin conditions characterized by inflammation and tissue oxidative stress in children, as PA with mild and moderate AD.

BACKGROUND: MAS063DP cream has received marketing authorization in the USA and the EU as a medical device for the relief of symptoms of atopic dermatitis (AD) and contact dermatitis. OBJECTIVE: Review of technical and clinical data in the literature on MAS063DP to evaluate the role that MAS063DP (Sinclair Pharmaceuticals Ltd) holds in the management of patients affected by AD. METHODS: We explored the characteristics and efficacy of the product by a wide-ranging search of the medical and scientific studies in the literature and drew our conclusions also on the basis of our medical practice and knowledge concerning the treatment guidelines and therapy options of AD. CONCLUSION: MAS063DP is a product dermatologists could enroll in the treatment of signs and symptoms of mild-to-moderate AD in adult and pediatric patients.

Acupuncture versus pharmacological approach to reduce Hyperemesis gravidarum discomfort.

AIM: Several reports have suggested the use of acupuncture as a useful treatment for hyperemesis gravidarum (HG), in particular the effects on nausea intensity was underlined. The aim of this study was to compare the efficacy of acupuncture sessions plus acupressure with a metoclopramide/vitamin B12 treatment. METHODS: In this study we randomized 88 pregnant patients suffering from HG to receive either acupuncture sessions plus acupressure (acupuncture group) or metoclopramide infusion (metoclopramide group) supplemented by vitamin B12 complex. Somatic symptoms and the ability to achieve the daily routine activity (functioning) were evaluated. Acupuncture sessions were performed at the hospital twice a week for 2 weeks according to the traditional Chinese medicine criteria. Acupression was applied for 6-8 h/day. In the metoclopramide group, patients received at hospital metoclopramide infusion (20 mg/500 mL saline for 60 min) twice a week for 2 weeks. An oral supplementation with vitamin B12 complex (30 mg/day) was also prescribed. RESULTS: Both treatments reduced vomiting episodes and then nausea intensity with a consequent improvement in the rate of food intake. The effect of acupuncture seems to be progressive, increasing at the end of treatment whereas pharmacological approach has a prompt effect in responders remaining stable thereafter. Moreover, acupuncture was significantly more effective than drugs in improving functioning. CONCLUSIONS: In our study for the first time acupuncture, applied accordingly to Chinese formula, was compared to drugs demonstrating the same effect of both treatments on HG symptoms. Interestingly, functioning was significantly improved just by acupuncture. Even if the effect of acupuncture on HG discomfort remains to be confirmed, the reports on the effect of acupuncture on psychosocial variables could represent a further advantage of acupuncture application and provide an incentive to widen the base of the research.

Effects of acute L-arginine infusion on non-stress test in hypertensive pregnant women.

OBJECTIVE: The present report evaluates the effect of acute L-arginine administration on fetal heart variables by a computerized non-stress test (NST) analysis. METHODS: Fifteen pregnant women at 30-34 weeks of gestational age affected by mild to moderate gestational hypertension were enrolled in the study. The study was performed in the second and third days of hospitalization. Each woman received both active (Arg) or placebo treatment (Placebo), in a double-blind, randomized, cross-over design. Women received saline infusion for 40 min, then they were infused with either placebo (saline infusion prepared by Damor Pharmaceutics and labeled as Arg-B) or Arg (L-Arg 20 g/500 ml labeled as Arg-A). RESULTS: Multiple analysis of variance (MANOVA) indicated that both placebo and Arg infusion were unable to affect cardiac variables and fetal movements. As far as maternal blood pressure changes were concerned, MANOVA indicated that active treatment showed an acute hypotensive effect on both systolic (F=8.98, p<0.001) and diastolic values (F=15.78, p>0.001). Conversely, placebo infusion does not seems to have induced any change. Considering each time of infusion we observed that Arg treatment was able to lower systolic and diastolic blood pressure after the 40 min of infusion, with this effect persisting for 20 min. CONCLUSIONS: These data indicate that the acute, intravenous administration of high-dose L-arginine does not induce significant changes in fetal heart rate (FHR), whereas it lowers maternal blood pressure. Such conclusions are reinforced by the observation that saline administration in the same pregnant women was neutral for both FHR and maternal blood pressure values. According to previous studies, it seems conceivable that maternal L-arginine treatment enters the fetal circulation by crossing the placenta. The lack of changes in FHR, however, suggests that no significant hemodynamic changes were induced by the treatment. Contrary to what happens in the mother, this may possibly be due to a low, if any, conversion of L-arginine to nitric oxide in the fetus.

Acupuncture plus moxibustion to resolve breech presentation: a randomized controlled study.

OBJECTIVE: In many Western countries breech presentation is an indication for elective Cesarean section. In order to correct fetal presentation, the stimulation of the acupoint BL67 by moxibustion, acupuncture or both has been proposed. Since no studies had previously been carried out on Western populations, pregnant Italian women at 33-35 weeks gestational age carrying a fetus in breech presentation were enrolled in a randomized, controlled trial involving an active BL67 point stimulation and an observation group. METHODS: A total of 240 women at 33-35 weeks of gestation carrying a fetus in breech presentation were randomized to receive active treatment (acupuncture plus moxibustion) or to be assigned to the observation group. Bilateral acupuncture plus moxibustion was applied at the BL67 acupoint (Zhiyin). The primary outcome of the study was fetal presentation at delivery. RESULTS: Fourteen cases dropped out. The final analysis was thus made on 226 cases, 114 randomized to observation and 112 to acupuncture plus moxibustion. At delivery, the proportion of cephalic version was lower in the observation group (36.7%) than in the active-treatment group (53.6 %) (p = 0.01). Hence, the proportion of Cesarean sections indicated for breech presentation was significantly lower in the treatment group than in the observation group (52.3% vs. 66.7%, p = 0.03). CONCLUSIONS: Acupuncture plus moxibustion is more effective than observation in revolving fetuses in breech presentation. Such a method appears to be a valid option for women willing to experience a natural birth.

L-arginine infusion reduces blood pressure in preeclamptic women through nitric oxide release.

OBJECTIVE: This study investigates the biochemical and cardiovascular effects of L-arginine administration in normotensive pregnant women and women with preeclampsia. METHODS: The study groups consisted of 12 women with uncomplicated pregnancies and 17 preeclamptic patients, four of whom were on antihypertensive treatment. In both groups, saline infusion was started, followed by 30 g L-arginine administration, and finally more saline. Blood pressure was recorded every 5 minutes and blood samples were collected for measurement of serum citrulline, arginine, and nitrite levels. Amino acid assays were done by using high-performance liquid chromatography with fluorometric detection. RESULTS: L-Arginine infusion was associated with a significant reduction of blood pressure in both groups, the decrease being greater in the women with preeclampsia. Baseline serum citrulline and arginine levels were not significantly different between the two groups. L-Citrulline levels were significantly increased during infusion of L-arginine, and the increase was significantly lower in the women with preeclampsia. Serum nitrite levels were increased only in controls and not in preeclampsia patients. The total citrulline production stimulated by L-arginine was related inversely to baseline blood pressure values and was unrelated to clinical parameters such as gestational age at delivery, birth weight, and Apgar score. CONCLUSIONS: L-Arginine load in pregnant women is associated with increased nitric oxide (NO) production and hypotension. Despite a reduced ability to produce NO, patients with preeclampsia may benefit from L-arginine supplementation. Overall, these findings partially support the hypothesis that preeclampsia is characterized by a dysfunction of the L-arginine-NO pathway.

L-arginine infusion decreases platelet aggregation through an intraplatelet nitric oxide release.

Nitric Oxide (NO) inhibits platelet aggregation via activation of an intraplatelet soluble guanylate cyclase which induces an increase in cyclic GMP (1). It has been also demonstrated that platelets contain a constitutive, calcium-dependent, NO synthase which is activated by collagen-induced platelet aggregation. This leads to a NO synthesis from L-Arginine (L-Arg), which in turn increases cyclic GMP and down-regulates platelet aggregation (2). In vitro administration of supraphysiological concentrations of L-Arg enhances platelet cyclic GMP levels by increasing NO production and reduces platelet aggregation. This effect is reversed by pre-incubation with NO-synthase inhibitors (3). These results indicate that the L-Arg: NO pathway plays an important role in the modulation of human platelet aggregation (4). In vivo L-Arg, when administered i.v., induces hypotension (5) and vasodilatation (6,7) in humans, and when orally supplemented reduces platelet aggregability both in hypercholesterolemic rabbits and healthy men (8,9).

Effects of a yeast-based dietary supplementation on premenstrual syndrome. A double-blind placebo-controlled study.

A dietary approach has proven to be effective in alleviating symptoms of premenstrual syndrome. In our previous studies, magnesium improved premenstrual irritability and mood scoings. In this double-blind, placebo-controlled study, we evaluated the effects of a new dietetic preparation (Sillix Donna, Giuliani) in 40 patients affected by mild to moderate premenstrual syndrome. Premenstrual symptoms were scored in both follicular and luteal phases, at baseline, at 2nd, 4th and 6th month of treatment by using the Menstrual Distress Questionnaire (MDQ). Twenty patients were randomised to receive the active preparation and 20 placebo. MDQ scores at baseline were similar in the two groups. Five patients of the placebo group dropped out because of treatment failure. No side effects were observed. Both treatments reduced symptoms already in the 2nd month, but the active preparation was more effective at all time controls (p < 0.05); at the 6th month it significantly reduced premenstrual MDQ scores to 18% of baseline values, placebo only to 73%. These data demonstrate that Sillix Donna is effective in reducing premenstrual distress.
